To all whom zt-may concern.'

Be it known that I, CURT KUENTZEL, subject of William Il, Emperor of Germany, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Wrapping and U11- wrapping Machines, of which the following is a specification.

This invention relates to machines for wrappingand unwrapping a strip of ma` terial about either a continuous object such as a cable or an annular tire or tire shoe. ,4

The machine is especially adapted `for wrapping and unwrapping tires before and after the vulcanizin and unwrapping tires for shipping .purposes, also for covering and uncovering wires and cables with pa er, tape'and cloth; finally for wrapping an unwrapping goods which are spooled incoils, such as wires and cables, hose, etc.

The ability of the machine for unwrapping wrapping material from t-he goods allows the ,spooling'up of the wrapping mai terial on spools, be used again without any extra spooling.

The primary object of this invention is to provide a new and improved machine for carrying out the foregoing objects and to so construct the device that it is capable of wrapping a strip of material about either a continuous or an annular object while revolving in one direction, and also capable of unwrapping the strip'of material from the object, provision being made for holding the bobbin against rotation on its own axis while being revolved about the object during the unwrapping operation and constructed that the bobbin may be rotated on its own :iris during the placement of the strip of material on the object. f

lVith the foregoing and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts constituting the'invention to be hereinafter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention but it is to be understood that changes, variations and modifications can be resorted to which come within the scope ot' the claims hereunto ap-.

pended.

For convenience of description of the con# struction of the mechanism shown in the accompanying drawingsbthe instrumentalities composing the machine will be grouped and will be described in their grouped relation. Thus, for instance, the mechanism for rotating an annular tireor tire-shoe to receive the supply of material will be described under the vgeneral heading of feeding mechanism and the description of the mechanism for yap lying to 0r removing a strip of material rom the tire or other object will be described under the general heading of winding mechanism.

Feeding mechanism.'-Tlie supporting ,means for the feeding mechanism embodies a pair of upright standards l and 2 spaced from each other and with bases 3, and alined heads or table-forming portions 4. The standards 1 and 2 are preferably provided with lateral walls (see Fig. 4). Extending between the bases 3 and the heads 4 of the two standards l and 2 are four upright posts 5 constituting guides on which is adapted to reciprocate vertically a carriage Gv. rllhe four guides 5 are arranged in pairs forming the corners of an imaginary square. The carriage 6 is provided at alternate corners with outwardly-extending lugs 7 provided withvertically-arranged threaded apertures therein through :which extend elevating screws 8 andf) mounted at their upper and lower ends in: the heads' 4 and bases 3, respectively, of the standards l and 2'. The screw S is provided at its upper end with a hand wheel 9 for the purpose of affording easy means of manipulation 'thereoi", and each of the screws 8 and 9 bear near their lower ends sprocket-wheels 10 -to receive a sprocket-chain 1l -whereby a simultaneous rotation of the two screws is obtained. The carriage 6 is provided with two side integral members 12 provided with apertures constituting bearings for horizontal parallel shafts 13, one only of which is shown in'Fig. 1. These shafts are separated from -each other a suitable distance and each shaft bears a roller 14 on which the tread portionof'a tire 15 is adapted to be revolved. Extending between the side members 12 of the carriage 6 is a' rotatable shaft 16 (see Fig.A 2) bearing at one end a hand-wheel 17 by which it is rotated. This shaft 16 is reversely-threaded and is adapted to carry a pair of supports 18 on which are mounted upright horizontally-rotating guide rollers 19 adapted to hold the tire 15 in position during its revolution.

In order to rotate the rollers 14 for revolving the tire 15 the -following mechanism isv employed: Rotatably mounted in the standard 2 is adriving shaft 20 provided with a clutch 21 which is thrown into and out of clutching relation through the medium of aflever 22. The shaft 20 bears a worm 23 (see Fig. l) adapted to mesh with a worm`whee1 24, (see Fig. 4), mounted on a shaft 25 (see Fig. 1) supported in bearings 26. Mounted on the shaft .25 is a sprocket-wheel 27 which receives a sprocketchain 28 adapted to extend around -a sprocket-wheel 29 mounted on a shaft 30 supported 4in bearin s 31 on the'right outer face of the side wal 5 of the standard 2. Mounted on the shaft 30 is a cone-pulley 32. Rotatably mounted in suitable bearings 33 on the side Wall 5 of the standard 2 is a horizontal shaft 34 which bears a cone-pulley 35. A belt 36 extends between and com municates motion from the cone-pulley 32 to the cone-pulley 35 and drives the shaft 34. Mounted in suitable bearings 37 on the wall 5 is a'rotatable, threaded shaft 38 and which bears a vmanipulating or hand-wheel 39 and also a flanged roller 40 which engagesfthe` belt 32V and constitutes a beltshifter for changing the* speed of the motion transmitted from the cone-pulley 32 to the cone-pulleyl 35.

Mounted on the shaft 34 is a'worm 41. Extending between the base y3 and the head 4of the standard 2 is a splined rotatable shaft 4,2, (see Figs. 1 and '4) fixedly secured to the-upper end of which beneath the head 4 is a Worm wheel 43 adapted to-intermesh withfthezwo'rm` 41 so that motion is thereby 'transmitted tothe shaft 42. Mounted on the splincd-.portion of the shaft 42 is'a beveled gear'f44adaptcd tointermesh with a beveledgea'r145 ontheshaft 13 of one of the rollers14. Both of the shafts 13 bear- 1s'pro'clcc"tiwhcels 46 (sce Fig. l.) between which extends a sprocket-chain 47,` (see Fig.

2) so that motion is simultaneously communicated to both of said rollers.

From the foregoing, it will be seen that when a tire, or tireshoe, for instance, is mounted on the peripheries of the two rollers 14 and motion is communicated through the medium of the clutch 2l to the drivingshaft 20, motion will be transmitted through the hereinbeforedescribed mechanism to these rollers for continuously revolving the tire or tireshoe 15 and which is guided in its revolution through the medium `f\the guide rollers 19.

Winding mechanism.-The mechanism for winding or unwinding a strip of material about the tire or tire-shoe during its revolution on the rollers 14 embodies the following mechanism: Mounted on the upper faces of the heads 4 of the standards 1 and 2, is a frame 50 which is roughly described as somewhat in the shape of a horseshoe with the open side or heel portions of the horse-shoe restin u on the heads 4. Rotatablysecured to t e ront face (in Fig.

-1) of the frame 50 are a lurality of flanged rollers 51, and revolub ymounted on the peripheries of these rollers 51 is a broken ring or annulus, the opening therein being approximately the same as the distance be tween the two separate portions of the frame 50. Also rotatably secured to the front face of the frame 50 are a second series of {ianged rollers 53 with the anges reversel -arranged-with respect to the flanges o the l rollers 51 and revolubly mounted on the peripheries of the rollers 53 is a second broken annulus 54, the ends of which are separated in the same manner and approximately the same distance as are the ends of the annulus 52. In practice, I customarily employA five rollers 53 so as to suitably support the annulus 54 throughout a compl terevolution. The annuli 52 and 54 a e eccentricallydisposed with reference to each other, that is to say, the axis of revolution of the annulus 52 will be, sa for instance, at 56, while the axis of revo ution of the annulus 54 will be at 55. The annuli 52 and 54 are provided with pins on which' are pivotally mounted links 57 for connectin them together whereby they both revo ve, but on different axes of revolution.

In order to revolve the annuli the followin mechanism is emplo ed: Mounted in a suitable bearing in the rame 50 is a shaft 58 on the rear end of which is Aa sprocket wheel 59 (see Fig. 2) which is adapted to receive a sprocket chain 60 the opposite end of which is arranged to run on a sprocket wheel 61 on the shaft 25. Mounted -on the front end of the shaft 58 is a pulle 62. Mounted on the opposite side of the 'rame 50 is a shaft 63 on whichis an ,idle4 pulley 64. Mounted on the outer ortionsl of the frame 50 are other idler pu leysl 55, 66, 67

6; collar 80. Between t '67, `-66 and 65 and back to the and 68, (see Fig. 3) approximately polygonally positioned. In order to transmit motion .to the annuli from 'the pulley 62, a belt 69 is employed which is carried around the pulley 62 and `from thence over the outer ace of the annulus 54 to the idler pulley 64 and from thence around the idler pulleys 68, pulley 62. In order to maintain this belt at the proper' tension4 at all times a tension device 70 of any ordinary construction, is employed.l

he operation of the foregoing mechanism it is thought will be apparent from the de scri tion, 'but 4for clearness it is amplified as ollows.: AMotion is communicated from the shaft 25` throu ythe sprocket-chain `60 to the shaft 58 andl from thence by means of the belt,69 to'lthe shaft 58 and from thence lb means of the belt 60 to the annulus-54 wich as it-revOl-ves causes a simultaneous, but eccentric revolutiongof the annulus 52.-

Bobbi,` #mendiants,mh- Reference is here directed to Figs. 4, 5 and 6. In the upper portion of the annulus 52, as the parts are arranged in thedrawings, is an aperture in which is ivotally -mounted a wrist pin 71 of a link 72 the upper en'dof which is 'provided with an aperture in which is ositioned thehead 73 of a shaft 74. The shaft 74 is freely mounted in a suitable bem ing in the upperportion of the annulus 54. The link 72 is provided 'with an aperture to re' ceive the vhead -73 and extending vfrom said aperture is an opening 100 which is also provided with 'a parallel groove 101v` the opening 1001 communicating with the aperture in the link 72 Awhich receives the head 73. The lower portion of the opening 100 is provided. with v an enlargement 102. A locking pin 75 is provided and arranged to be inserted in the opening 100 and extended into a suitable aperture 103 (see Fig. 7) in the head 73 for locking the member 74 against independent rotation. The pin 75 is provided with a laterally-projectng lug 10Jr adapted to be passed through the longitudinal groove 101 and when given a' partial rotation to lock itself within the enlarged opening 102 against withdrawal and in order to withdraw the in when desired and when the lug` 104 is 1n registering relation with the longitudinal groove 101 a resilient element such as a spring,T 106 is provided. The forward end ofthe shaft 74 provided with a pair of ears 76 in which mounted a pin to constitute a hinge for a bobbinshat't'77, which is thereby pivotally mounted thereon. Mounted on the hobbin .shaft is a sleeve 78 held in'position by some means such for instance as a washer and a nut on the end of the shaft 77. Slidably mounted on the sleeve 78 is a bobbin 79 which is held in an adjusted position by means of a e ears 7G and the rear l face of the bobbin 79 is a tension spring 81 which is arranged to resist rotation of the bobhin and the tension of which can be adjus-ted by shifting the bobbin away from the spring and securing it through the medium of the adjustable collar 80.

In operation, if it is desired to wind al strip on a tire 15, or on a cable extended centrally through the space inclosed by the frame 50 the pin 75 is raised suiiiciently to disconnect the crank 72 from the head 7 3 of the bobbin shaft leavingthe bobbin free to revolve as the strip of material is un- Wound therefrom while the bobbin is lmoving orb.;y ally about the tire 15 and of course, the degree of tension which is placed on the strip` of material during itsplacement will be determined by means of the tensionspring 81. If it is desired to unwind or remove a strip of material from a tire or any object'arranged axially of the opening in the frame 5U, 'the pin 7 5 is forced inwardly so as to interlock the link 72 and the head 73 of the bobbin-shaft 74, which holds thel bobbin fixed against independent rotation during its revolution about the tire and as it moves orbitally about the tire it will wind or take up a strip of material from the tire during its travel.

' It will be obvious that a plurality of bobbins may be employed instead of one, and thatas thel single bobbin moves orbitally about ythe vtire with the pin 75 in the position shown in Fig. 5,;the rotation of the bobbin is prevented and the relative posi, tion of the Various parts thereof will always" lgemein th-e same, thereby enabling the bob- 1n vclves about the tire. As tires with their inclosed cores are exceedingly heavy, provision is made for a loadingr and unloading platform which can be shifted in unison with the carriage 6 and in order to accomplish this loading and unloading of the tires the front and rear faces of the carriage 6 are provided with eyes 82 into which hooks 83 of platforms 84 are engaged for raising and lowering'themin unison with the carriage 6. The outer or extended ends of the platforms 84 are provided with rollers 85 to permit them to shift their position in unison with the changes of position of the inner ends of the platforms.

When it is desired to )vind a strip of material on an object, one-end of the strip is loosened from the spool of material on the bolibin and attached tothe tire and the shut-- tle ifomposed of the two broken annuli are moved about the object as the latter is fed through the space inclosed by thc frame 50. ln doing` this, a proper degree of tension is imposed on the bobbin by means of the spring 81 and its free rotation is therein' braked. l

rotation of the bobbin ltself. As the spool moves orbitally aboutthe object and is itselfl prevented from rotation, it rapidly winds up the strip of material from the object.
